Great addon to complement the Nord VPN Desktop app in case you want to control when you activate VPN and which websites are whitelisted, but it has few issues:

1. There is no easy way to whitelist websites, apart from clicking on the extension, going to settings, going to Bypass List, copying and pasting the website url (needs to have http:// otherwise it won't work) then saving and reloading the website. They need to make this easier by having an option while right clicking the page or by having a simple "add to whitelist" button in the extension menu, like ad blockers do.

2. There are to blacklists. It would be useful to have the option to run the extension in either whitelist or blacklist mode and select which websites to be tunnelled and which to be not. Right now there is only whitelist option.

3. Ever since the recent Firefox update to version 89, the extension randomly stops working, it will not login into the account anymore. The solution is to remove the extension and add it back again which is a pain because all the whitelisted website are gone and there's no obvious way to back them up. I'm not sure if it's an additional Firefox settings that is causing this problem or the Nord VPN extension hasn't been updated yet, but once every 2-3 days I have to do this.

Overall I'm happy with it, but Widnscribe has more settings and is easier to use. Not as reputable as Nord VPN, but Nord could make the extension a bit more feature-rich.
